PEA-SHELLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 700,476, dated May 20, 1902. Application filed September .10, 1901. Serial No. 74,871. lNo model.)

T0 @ZZ whom it Vmay concern:

Be it known that I, THEoDoRE BossHARD, a citizen of the UnitedStates, residing at the borough of Brooklyn, inthe county of Kings and State of New York, have invented an Im-v provement in Pea-Shelling Machines, of which the following is a specification.v

The device of my present application comprises improvements upon similar machines heretofore employed by me, and. especially upon the devices shown and described in my application for Letters Patent, led. October 20, 1900, Serial No. 33,727,` and allowed May 11, 1901.

The 'object of my present invention is to simplify the mechanism and to make the machine more efficient and. serviceable.

In carrying` out my invention I provide a 'case along4 and through which a conveyer or endless belt is moved toconvey the peap'ods from a hopper at one end of the casato separating and. progressing devices and nipping-rollers at the otherhend of the case.` In my improvement the feeding-aperture from the hopper for the pea-pods is adjustable by a moving plate, and. I provide means for bodily moving the hopper to tighten the belt em-4 ployed for rotating 'a cylinder at the base of'V the hopper which progressively feeds the peapods from the hopper to the conveyer, and at the other end 'of the case the nipping-rollers,

roller are geared together, so as to beactua'tedj from a common source of power, and the parts at this end of the machine are so'constructe'd and'conn'ccted that they are easily separable, not only-for the purpose of cleaning, but for preventing the clogging: up of the machine,

ing the peas as separa-ted from the'podsand andforming a sifter through which thepeas may pass yand any pods escaping into the In the drawings, Figure 1 isa broken vertical section, and Fig. 2 abroken plan, represection on 'the vertical line w a; of Fig. 1.

up endwise.

Fig. 5 is a plan of the parts shown in Fig. '4, y

` longitudinally of th and Fig. 6 is an elevation of 'the adjustable bearing at one end of thefconveyer. Y

The case ct comprises abottom plate and side parts thatare parallel to one another and 55 i partial end parts, the same being of general rectangular form and provided with a drawer b, passing in from one end and being practically of the length of the case and adapted to receive the peas as separated from the' 6o pods. I employ a wire netting 2 of large mesh covering over a portion of the open part of the drawer near the outer end, so as to form y of the drawer and wire-nettinga sitter, the meshV being large enough to permit the peas 65 to pass through the same and to retain in the drawer any wholepods or parts of pods that may not have passed through the machine, and. it will be readily seen that this sifter device may be brought into operation when the 7o drawer is removed fro'mthe'case and turned.v

This conveyer passes around a ,roller v7 5 3 at one end, the axleof the rollerbeing received inadjustable yoke-bearings 4, pass- 'y ing into the sides of the caseand having nuts by/which the stemsof the bearings1may be` y moved longitudinallyto apply Vte1`1sion to, the 8o. conveyer. The saidconveyercpassesarourid a roller r'attheother' end. of thecase, and;

this roller 5 isjjournaled in bearin'g-.platescl `cliwhi'ch'plates are advantageously,received in notches'or.recessesmade in'the'sid'es, the 85 Y said plates being let down into the' sides and. g Y' retained inv place, as hereinafter'spejcied.

The shaft'of the roller 5 is provided witha pinion or gear.. 6 atoneend,and. .Iemploy' f pulleys ee', around; whichipasses'. a lcrossed 9o4 fbelt 7,th'e pulley e.being'npon'the"shaftof v -theroller Sand-'the' pulley e'upon the shaft I' of` a cylinder f, which cylinder isiprovided at' spaced -apart intervalswithfprojecti'ng ,n 5 v1 pins 8 L. x95'- i The hopper g is provided with a base g', to `i 1 which the same ishinged, andthe Abase is provided over the sides fofthefcase with'ta'- pering ribs engaging undercut ribs 110.0 1'1 the ,y v Y upper 'surface of the'case, said ribs forming y:et: slideways for the hopper and. the hopper-b' e:

' ase 'The hoiipr not only hinged to the hopper-base g', but the parts are connected in their relation to one another and so held, preferably, by a hook or equivalent device 26, and as the cylinderfis journaled in the hopper-base g/ the hopper may be swung over after being released by the device 26, so as to separate the parts for cleaning or in case the same becomes partly choked.

I provide screws S), passing through one end of the case and nuts connected therewith and bearing at their ends against one end of the hopper-base, and as the cylinder is journaled in the hopper-base it is apparent that the movement of the screws 9, shifting the hopper-base, will apply tension to the belt 7 to tighten the same upon the pulleys. lVithin the hopper and extending across the machine I provide a plate 12, hinged to the upper edge of the hopper, and a strap or equivalent device 13, attached to the lower free edge of said plate, passing through the hopper and having holes to connect the strap to a pin, as shown. By the operation of this strap said plate is moved and permitted to occupya graded relation to the cylinder f, so as to decrease or increase the opening Within the mouth of the hopper, and thus regulate the opening through which the peas pass from the hopper onto the conveyer c.

In the hopper I provide a stirrer 14 in the form of a rod extending over the upper edge of the hopper, with a handle portion outside of the hopper and passing through an eye secured to the inner surface of the hopper. This stirrer may be moved about within the hopper by hand, so as to loosen up the peapods in case the hopper becomes at all choked. I provide a pair of delivery-rolls 7L 7L', pivoted in the bearing-plates d d. These rolls are connected together at one end by meshing gears 1G, and at the other ends of said rolls a crank and handle 15 are secured on the shaft of the roll h.

I provide ilanged side plates i '12', preferably of metal and of inverted-L form, the longer portions lying within and adjacent to the sides of the case and the shorter portions resting horizontally upon the upper edges of the sides. A roller k is journaled in these side plates 115i', and the ends of the shaft of said roller pass through notches in the upper edges ot' the plates d d', and there is a gear 17 on one end of the shaft of the roller k, meshing with a gear 23`intermediate thereto and to the gear on the roll t', and I provide a further gear 24, that is intermediate to the gear of the roll h and the pinion or gear G, so that by the crank and handle 15 the rolls h z are revolved together with the roller 7c, the roll 5, and by the rotation of the roll 5 the conveyer or endless belt c is moved, and through the same and the belt 7 and pulleys c e the cylinder fis revolved to feed the pea-pods from the hopper onto the conveyer. This roller 7.; is provided with radial iiexible blades 1S, that extend the length of the roller between the sides of the ease, and these blades are notched at spaced-apart intervals, practically dividing the flexible blades up into independent lleXible fingers, and I provide a cover 19 over the roller 7c, connected to the flanged side plates 'L' 1T', and which cover also forms an end to the case above the deliveryrolls 7L 7i to prevent the escape of any peapods above the said rolls.

A transverse bar Z extends across between the sides of the case andA is connected to the plates t fz, and separator-iingers 2O are secured to the said transverse bar l and extend longitudinally of the case above the conveyer, dividing the space between the sides above the conveyer into three portions. The iianges of these side plates t' t" are preferably prolonged at one end and notched to pass beneath portions of pins 21 or equivalent de vices, that are fastened in the upper surface of the sides, and latch-bars 22, pivotally connected to the sides, are adapted to swing over upon the flanged side plates after the same are in position, so as to hold the same to the case of the machine.

In the operation of the pea-shelling ma chine the plate 12 is to be adjusted according to the size of the pea-pods, and the strap 13, connected thereto, may be secured and held in any desired manner. I have shown holes in the strap and a pin on the hopper for this purpose. The pods are placed in the hopper and the mechanism set in motion by the crank and handle 15. The pods are progressively fed from the hopper by the cylinder f and its pins down upon the moving conveyer. The said conveyer carries the pods along, and as the pods come up to the fingers 20 the latter act against the pods to shift their position, so as to bring them approximately lengthwise of the case and present them Aendwise to the roller 7o. There is an appreciable space between the surface of the conveyer and the edges of the flexible blades 18, and these blades engage the pods and advance the same positively toward and against the rolls L h. These flexible blades may possibly in practice have more or less of a tendency to separate the parts of the pods, and as the pod lengthwise will in practice be engaged by several ot' these ilexible blades there is a tendency to separate the peas from the pods, the main separation, however, occurring through the action of the delivery-rolls h 7L', as these rolls nip the pods and run suilieiently close together to hold the pods tightly and force the same through between the rolls, pressing out and separating the peas from the pods. 'Ihere is a space between the end of the conveyer adjacent to these rolls and the end of the case, and the peas as separated from the pods pass through this space down into the drawer l), and the pods as they pass through between the rolls 7L h fall over an incline 25, which I prefer to employ and make a part of the case, so as to divert the pods into a suitable receptaclo. After the shelling operation TOO IIO

IIS

the drawer b is removed with the peas, and should there be any whole pods orfparts of pods orpieces the peas lmayi be separated or sifted therefrom by passing the same through the wire-netting 2, covering a portion of the drawer at the forward end thereof.

The flanged side Yplates it', the roller 7c with its ,blades 18 andthe gear 17, the cover portion 19, the transverse bar 1, and the fingers 2O are connected so as to be. collectively removable from the case of the machine by the swinging of the latch-bars 22. The transverse bar Z-is so placedbetween the side plates c' i that its under edge is above the surface of the conveyer a distance that approximately agrees with the thickness of a pea-pod. This construction acts,further,to separate the pods as they pass along on the conveyer between the ngers 2O andprevents superposed pods passing into the machine, compelling the pods to pass single' depth upon the conveyer, and- I prefer to make theopposite vertical edges of the bearing-plates d dpointed or V-shapedv and to cutthe vertical'edges o f ythe recesses in the sides of the case receiving said plates correspondingly. This prevents lateral movementof the said plates and the parts connected therewith, .butdoesnot hinder the vertical; movement in removing the same from the case or putting the same in place.
